Let's start by solving the first equation.
a) -3 = 7 + 2t/3
To begin simplifying this equation, we should multiply both sides by 3 to get rid of the denominator on the right side of the equation.
-9 = 7 + 2t
Next, we should subtract 7 from both sides to cancel out the 7 on the right side.
-16 = 2t
Finally, we should divide both sides by 2.
t= -8
Now let's move on to the next equation.
b) 4(5x-2) = 7(2x+3)
Let's use the distributive property to get rid of the parentheses and their coefficients.
20x-8 = 14x + 21
Now, lets subtract 14x from both sides of the equation.
6x - 8 = 21
Next, let's add 8 to both sides of the equation.
6x = 29
And divide both sides by the coefficient of x, which is 6.
x = 29/6 or 4 5/6
Now for the last equation.
C) 2x - 6 = 20 - 2.5x
First, we should add 2.5x to both sides to cancel out the -2.5x on the right side of the equation.
4.5x - 6 = 20
Now, let's add 6 to both sides to get the variable term alone.
4.5x = 26
Finally, we should divide both sides by 4.5 to get x by itself.
x = 5 7/9
Hope this helps! :)

Answer:
15 per hour
Carl earns more
Step-by-step explanation:
Carl's earnings = earnings/no ofhours
We select any hour and corresponding earnings say 150 and 10
Earning per hour of Carl = 150/10 = 15 per hour.
b) Carl earns more as 15 >12 hourly rate of other person
c)
<h3>
Answer: 471,744,000</h3>
Delete the commas if needed. This is one single number between 471 million and 472 million
===========================================================
Explanation:
We have 26 letters for the first slot, then 25 for the second, and 24 for the third. We count down like this because we cannot reuse letters.
There are 26*25*24 = 15,600 ways to pick the three letters where repeats aren't allowed.
As for the numbers, we have 10 single digits (0 through 9) for the first numeric slot, then 9 for the next, and so on until we reach 6
So we have 10*9*8*7*6 = 30,240 ways to select the five numbers.
In all, there are (15,600)*(30,240) = 471,744,000 different license plates possible. This number is between 471 million and 472 million.
This is a division problem.
6/20 = 0.3
